Description

Title of the invention: ROBOTIC TRANSPORT ARM Technical field

[0001] The present invention relates to the field of construction machinery, and relates to a robotic transport arm.

[0002] Large-scale devices such as forklifts and excavators are widely used in the infrastructure and construction fields and play an important role. However, for some specific construction fields, due to the terrain environment and operating requirements, the implementation and operation of these machines are difficult. For example, in the construction process of rural villas, stones must be moved one by one to a specific location in the foundation. It is inconvenient for an excavator to operate under conditions of limited space and complex environment. In addition, with regard to a simple stone, its weight varies from a few kilograms to one hundred kilograms, and its structure varies widely.

[0003] At present, there is no suitable device for transporting stones one by one. If the transportation is carried out by an excavator, its operation is complex and its performance is low in terms of cost, and even the resources of the excavator will be wasted. Therefore, current practices all rely on manpower to carry out the transportation, but there are still problems such as labor consumption, time consumption, and intensive work.

[0004] The object of the present invention is to solve the problems existing in the prior art by providing a robotic arm. PRESENTATION OF THE INVENTION

[0006] According to one aspect, a support protrusion is provided at the bottom of the blade near the limiting plate, and the blade can rotate with the control rod around the support protrusion.

[0007] According to one aspect, a pair of rollers are provided at the bottom of the blade, the supporting protrusion is configured as a roller shaft; two ends of the roller shaft are respectively provided with one of the rollers.

[0008] According to one aspect, two control rods are respectively fixed on either side of the limiting plate, and a discharge opening is formed between the two control rods and the limiting plate.

[0010] [Fig.l] is a schematic structural diagram of a robotic arm according to one embodiment of the present invention;

[0011] [Fig.2] is an enlarged structural diagram of part A of [Fig.l]. DETAILED DESCRIPTION OF THE INVENTION

[0012] In order to make the objectives, technical diagrams and advantages of the present invention more clear, the present invention will be explained in more detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein serve only to explain the present invention, but not to limit it.

[0013] As shown in [Fig.l]-2, wherein [Fig.l] is a structural diagram of a robotic arm according to an embodiment of the present invention; [Fig.2] is an enlarged structural diagram of part A of [Fig.l].

[0014] The present invention relates to a conveyor robotic arm comprising a blade 1. A feed inlet 2 is provided at one end of the blade 1, and the blade 1 is connected to a limiting plate 3 on its side away from the feed inlet 2. The limiting plate 3 is provided with a control rod 4, and a support frame 5 is arranged on the blade 1 near the feed inlet 2. The support frame 5 is provided with a plurality of parallel rotating shafts 6 and a locking rod 7. Each of the rotating shafts 6 is provided with a clamping plate 8 rotatable around the rotating shaft 6. The lengths of the clamping plates 8 on the different rotating shafts 6 are gradually shortened according to a gradient in a direction near the feed inlet 2, and the shortest one or more clamping plates 8 are in measure to come into contact with the locking rod 7.

[0015] In the embodiment of the present invention, the clamping plate 8 is hinged to a rotating shaft 6 at its top, and the clamping plate 8 is provided with toothed clamping teeth extending in a direction close to the blade 1 at the bottom of the clamping plate 8. Several clamping plates 8 of the same dimensions are to be arranged on the same rotating shaft 6. In the direction close to the feed inlet 2, the lengths of the clamping plates 8 on the rotating shafts 6 are shortened in a gradient. It is easy to understand that this arrangement ensures that all the clamping plates 8, from the longest to the shortest, can smoothly contact the surface of the material after the material to be introduced into the feed inlet 2 (taking the stone as an example) passes through the clamping plates 8. The shortest clamping plate 8 can bear against the locking rod 7.It is easy to understand that the locking rod 7 is arranged to ensure that a tilting stroke of the clamping plate 8 stops in a vertical position and presents the tilting stroke in a direction away from the feed inlet 2. Furthermore, the number of the clamping plates 8 and the gradient in which the clamping plates are shortened can be determined according to actual situations and experiments.

[0016] In the practical application method of the present invention, the control rod 4 can be fixed on a mechanical power structure. In the propulsion process, the stones are moved toward the blade 1 and are limited by the clamping plates 8, especially during a lifting operation. After the stone transportation is completed, the control rod 4 is tilted or ejected, and the stone can be smoothly dumped or removed from one side of the limiting plate 3. Therefore, the present invention can be used as a front-end robotic arm of an existing excavator or the like to complete a smooth and rapid gripping operation of irregular items.

[0017] In another implementation process, in order to facilitate the stone dumping operation, a supporting protrusion (the reference number is omitted in the figure) is provided at the bottom of the blade 1 near the limiting plate 3, and the blade 1 pivots with the control rod 4 around the supporting protrusion. In the actual application process, by simply pressing the control rod 4, the blade 1 will be tilted upward around the supporting protrusion. Under the action of gravity, the stone will pass through the limiting plate 3 to complete the dumping operation.

[0018] In another implementation process, to facilitate manual operation, the transport robotic arm of the present invention may be implemented in the form of a transport trolley. More specifically, the blade 1 is provided with a pair of rollers 9 at its lower part, and the supporting protrusion is configured in the form of a roller shaft. Two ends of the roller shaft are respectively provided with one of the rollers 9.

[0019] According to the rational design, in the embodiment of the present invention, more specifically, two control rods 4 are respectively fixed on both sides of the limiting plate 3, and a discharge opening is formed between the two control rods 4 and the limiting plate 3.

[0020] In the practical application method of the present invention, workers can use the blade 1 to pry and the clamping plate 8 to clamp through the tilting of the control rod 4 to realize the loading of the stones, and use the rollers 9 to realize the movement of the device and the transfer of the stones. Finally, after the control rod 4 is pressed to be horizontally fixed on the ground, the limiting plate 3 is in an inclined state, so that the stones can roll from the unloading opening.

[0021] Therefore, the present invention has a simple and small structure, is suitable for manual operation under the working conditions of limited space and complex environment, and is convenient to use, saving time and labor.

[0022] The foregoing describes only preferred embodiments of the present invention, but is not intended to limit the present invention. All modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included within the scope of protection of the present invention.
